/u003Cp dir=/u0022ltr/u0022/u003EAnother key feature of the IS220PPDAH1A board is that it allows for corrective action to occur by sending and reporting information but it cannot take directive protection action. This board supports system maintenance by sending timely information to the PDM. /u003Cstrong/u003EThe PPDA board can receive feedback from up to six PDM components, most of these components are JPDx boards and will host the PPDA I/O pack./u0026nbsp;/u003C/strong/u003E/u003C/p/u003E
/u003Cp dir=/u0022ltr/u0022/u003EThe IS220PPDAH1A board uses electronic IDs to determine power distribution information, the information will then be used to populate the IONet outputs and provide the correct information and feedback to the conjoining boards./u0026nbsp;/u003C/p/u003E
/u003Cp dir=/u0022ltr/u0022/u003EPlease note that when the IS220PPDAH1A board is used in applications reading two hundred forty volts of alternating current it should not cross-connect with the volts of direct current; when this occurs the peak voltage will exceed the MOV rating and cause a failure./u003Cstrong/u003E Failures occur as most of the alternating current supplies must operate on a grounded neutral./u0026nbsp;/u003C/strong/u003E/u003C/p/u003E"}">
產(chǎn)品說明
配電反饋板IS220PPDAH1A是通用電氣公司生產(chǎn)的Mark VIe系列的一部分。該板是配電模塊的一部分，在這種配置下，它將為接地故障檢測(cè)、大容量電源健康、電源總線電壓和分支電路狀態(tài)提供反饋。該模型能夠具有完整的系統(tǒng)反饋和監(jiān)控，這使其不同于標(biāo)準(zhǔn)的配電方法。請(qǐng)注意，盡管該模型為分支電路提供反饋，但分支電路并不直接連接到PPDA組件。
IS220PPDAH1A板的另一個(gè)關(guān)鍵特性是，它允許通過發(fā)送和報(bào)告信息來采取糾正措施，但不能采取直接保護(hù)措施。該板通過向PDM及時(shí)發(fā)送信息來支持系統(tǒng)維護(hù)。PPDA板可以接收多達(dá)六個(gè)PDM組件的反饋，這些組件中的大多數(shù)是JPDx板，并將托管PPDA I/O包。
IS220PPDAH1A板使用電子id來確定配電信息，該信息將用于填充IONet輸出，并向連接板提供正確的信息和反饋。
請(qǐng)注意，當(dāng)IS220PPDAH1A板用于讀取240伏交流電的應(yīng)用中時(shí)，它不應(yīng)與直流電壓交叉連接；當(dāng)這種情況發(fā)生時(shí)，峰值電壓將超過MOV額定值并導(dǎo)致故障。由于大多數(shù)交流電源必須在中性點(diǎn)接地的情況下工作，所以會(huì)出現(xiàn)故障。
